Benefits of technology

The present invention is a device that regulates a person's temperature. It has two layers, an enclosure, and a liquid absorbing material. The layers are sealed together to form the enclosure, and there is a hole that allows liquid to enter. The liquid absorbing material is either positioned at the hole or on the outside of the device. The device is used to transfer the liquid's heat to a patient's skin. The technical effect of this invention is to provide a safe and effective way to regulate a person's temperature.

Problems solved by technology

Spilling liquids on a patient is undesirable.
Obviously, some thermal energy is lost when the thermal energy passes through the polymeric layer.
A problem with the rivet-like device is the liquid normally leaks.
Manufacturing a rivet containing thermoregulatory device has numerous quality control issues.
It is difficult to manufacture a thermoregulatory device with numerous apertures and each aperture being filled with a rivet-type device that does not leak.
As previously stated, a thermoregulatory device that leaks a liquid onto a patient is undesirable.

Embodiment Construction

[0020] The present invention is directed to a thermoregulatory device 10 interconnected to a fluid regulatory device 12 as illustrated in FIG. 1. The fluid regulatory device 12 provides a fluid having a predetermined temperature through a first conduit 13 to the thermoregulatory device 10. For this application, the fluid is a liquid and it is understood the fluid can also be a gas.

[0021] As illustrated in FIG. 2, the thermoregulatory device 10 has a first layer 102 and a second layer 104. The first layer 102 has a first interior surface 106 and a first exterior surface 108. The second layer 104 has a second interior surface 110 and a second exterior surface 112.

[0022] For this application, the first layer 102 contacts a patient. Since the first layer 102 contacts the patient, the first layer 102 has at least one aperture 105, preferably a plurality. If the fluid is a liquid, the liquid normally leaks from the apertures 105. To decrease leaking, a liquid-absorbing material 26 is po...

Abstract

The present invention is directed to a thermoregulatory device. The device has a first layer, a second layer, an enclosure, an inlet and a liquid absorbing material. The first layer has a first interior surface, and a first exterior surface. The second layer has a second interior surface and a second exterior surface. The enclosure is formed by sealing and / or attaching the first interior surface to the second interior surface. The inlet directs a liquid into the enclosure. The liquid absorbing material is positioned (a) at and / or near an aperture that allows a liquid to contact the liquid absorbing material; or (b) on the first exterior surface that is of a material that allows the liquid to contact the liquid absorbing material. In addition, the application is directed a method of using the thermoregulatory device to transfer the liquid's thermal energy from the enclosure to a patient's skin.

Description

FIELD OF THE INVENTION [0001] The present invention is directed to a thermoregulatory device. The thermoregulatory device is applied to a patient to alter the patient's temperature and / or maintain the patient's temperature. BACKGROUND OF THE INVENTION [0002] There are numerous types of thermoregulatory devices that alter and / or maintain a patient's temperature. One type of thermoregulatory device is Gaymar's T-pad device which has been existence since at least 1985. Gaymar's T-pad thermoregulatory device has a first polymeric layer and a second polymeric layer. The first polymeric layer has a first interior surface and a first exterior surface. Likewise, the second polymeric layer has a second interior surface and a second exterior surface. [0003] The perimeter of the first interior surface attaches and / or seals to the perimeter of the second interior surface to form an enclosure. The enclosure receives a fluid from a fluid regulatory device. An example of a fluid regulatory device ...
